Hello everyone, I'm happy to announce our next meetup will be hosted by [Productive](https://productive.io) (Strojarska 20, 5th floor). We'll have an interesting talk followed by a panel discussion, both centered around the challenges of "data imports". The panel brings together experts from a wide range of company sizes and language backgrounds, so we can explore the topic from hands-on implementation to broader business impact. Stick around afterwards for some food, drinks, and conversations. Hope to see you at Productive! \*\*\* **Data Imports** by Borna Artić At Productive, we import a lot of data, and doing it reliably has turned out to be trickier than it looks. In this talk I'll start with the "why": what imports solve for us, what kinds of data we bring in, and what we learned from earlier approaches. Then we'll walk through the current importer and the tradeoffs behind it: validating messy input, keeping complexity under control, and making it fast enough to run at scale. We'll also touch on edge cases like custom fields, missing relationships, and handling repeated data updates. **Panel: Data Imports Across Industries** Panelists: \- Josip Stuhli\, CTO at SofaScore \(PHP\) \- Dario Daić\, Product Architect at ButterflyMX \(Ruby\) \- Borna Artić\, Backend Engineer at Productive \(Ruby\) Moderator: Bruno Sutić After the talk, we'll keep the momentum with a panel discussion on data imports. We'll start from the hands-on problems you see in Ruby code, then zoom out to questions of architecture and long-term maintainability, and finally to the company-level impact: how data flows affect other teams, product decisions, and what the business can (and can't) do with the information it has. Expect a practical conversation with real tradeoffs rather than perfect answers. The panel brings together interesting people across seniority levels, company sizes, and language backgrounds.

At the last meetup, we examined WooCommerce under pressure. Security failures, AI agents behaving badly, and real examples of how stores get compromised. This time, we’re flipping the angle! The Winter 2026 Zagreb WooCommerce Meetup focuses on how the platform is being built and steered today. We’re hosting speakers from Automattic and the WooCommerce team to walk through recent platform updates, what’s currently being prioritized, and what’s coming next. You’ll hear what has shipped, what’s changing in key areas like checkout and blocks, and how upcoming work is likely to affect developers and merchants building on Woo. You’ll also get roadmap context straight from the people shaping it. Seeing these folks in person in Croatia doesn’t happen often! If you build, maintain, or sell on WooCommerce, this meetup should make your next set of technical decisions easier. **+++++++++++++++++++++** **Lecture 01** **\- What’s new in Woo: latest updates & what’s coming next** WooCommerce has been moving fast. Checkout extensibility, shipping and fulfillment changes, block-first experiences, the Interactivity API, and a growing layer of AI features are no longer “experimental” but becoming the default. In this talk, Brian and Shani will walk through the most important recent changes in WooCommerce and what’s coming next. Expect concrete examples, platform context, and guidance on how these changes affect real-world Woo builds. **Brian Coords** is a developer advocate at WooCommerce and a long-time WordPress developer, writer, and instructor. He hosts a WordPress podcast at Webmasters_fm and writes for WP Tavern, MasterWP, The WP Minute, and his own technology blog. **Shani Banerjee** is a developer advocate at WooCommerce, where she hosts monthly developer office hours and writes about platform updates and extensibility on the WooCommerce developer blog. Her work is shaped by a strong community-first background spanning support, software engineering, and education. **+++++++++++++++++++++** **Lecture 02** **\- The state of WooCommerce: where we are & where we’re going** In this session, Brent will zoom out and talk about how WooCommerce is positioning itself today: what’s driving the roadmap, how Woo thinks about high-growth merchants, and how the platform is evolving to stay competitive in an increasingly crowded eCommerce landscape. This is the “why” behind the updates which will help you understand the bigger picture: the product, market, and ecosystem context that rarely gets discussed outside closed rooms. **Brent MacKinnon** is director of product marketing and developer advocacy at WooCommerce (Automattic). He leads go-to-market strategy, developer relations, and analyst engagement, and focuses on making complex platform decisions understandable to builders and merchants alike. He’s based in Halifax, Canada. **+++++++++++++++++++++** **AGENDA** 18:00 - Meet & greet 18:05 - Talk: What’s new in Woo: latest updates & what’s coming next 18:40 - Q&A 19:00 - Talk: The state of WooCommerce: where we are & where we’re going 19:35 - Q&A After - Pizza & Beer 🍕🍺

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group × DevOps Columbus** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS, Columbus HashiCorp User Group, and DevOps Columbus meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/azure-cbus-2026/

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.
